Explanation:
This command specifies the zoom values for the main scan (i1) and the sub scan (i2) in the range of 50% to 200%. The zoom value increment is 1% or 10%, depending on the scanner model. See Appendix B for details.
When the zoom is set with the control panel, the zoom value of the main scan and sub scan are equal. The setting made with this command overrides the setting made from the control panel.
ESC H and other commands
When the scanner accepts this command, the scanning area is reset to the maximum value allowed with the current resolution and zoom settings. Always set the zoom before setting the scanning area.
See Chapter 2 for details on the software control procedures and on the use of the ESC R, ESC H, and ESC A commands. Also see the ESC A command.
